COTTON-PRESS.

SPECIFICATION forming part of Letters Patent No. 439,617, dated October 28, 1890.

Application tiled May 16, 1890.

To all whom it may concern.-

- reference bein g had tothe accompanying drawh ings, which form a part of this speciiication.

This invention relates to certain new and f useful improvements in apparatuses for compressing cotton and other materials, and more particularly in certain improvements upon the device described in an application for Letters Patent filed by me under date of January l5, 1890, Serial No. 336,980, allowed March 27, 1890.

These improvements consist,principally, in dispensing with the complicated gear mechanism embraced in said application for Letters Patent and substituting therefor the improved lever-lifting device, and also in providing suitable bracing devices, as will appear more fully hereinafter.

In the accompanying drawings, Figure l is a vertical sectional view of the complete device. Fig. 2 is a cross-sectional view on the line o: Fig. l; and Fig. 3 is a plan view of a portion of the movable platen.

Like letters of reference refer to like parts in all the figures.

Referring to the drawings, the workin g parts are shown as carried by a supporting-frame consisting of a base A, to which are secured four uprights B, said uprights being supported by longitudinal braces O C. These uprights are also united at their upper ends by means of a cross-head D,which forms the stationary platen of the press. The inner angles or corners of the uprights are faced by metallic strips E, which serve as tracks for a movable platen F, thus preventing the wear which would otherwise ensue to the uprights, and at the same time affording a smooth surface for the reciprocation of the platen. The upper portion of this platen, it will be observed, has extended reduced ends f, provided with Vangular notches f', which contact with the tracks before mentioned and form the upper bearing-surface of the platen.

Serial No. 352,067. (No model.)

Depending from the under side of the plate is an arm f2, which terminates at its extreme lower end in four auxiliary arms f3, between which are journaled the ends of an anti-frictional roller G. This depending-arm has also secured to opposite sides thereof arms H H, said arms having their ends bent into angular form and adapted to engage the tracks of the uprights, thus, in connection with the upper extended ends of the platen, forming a firm and steady support for the latter in its vertical line of movement.

` The base A has secured near opposite ends cleats I I, to which in turn are secured brackets J J', the latter being approximately U shape, so as to provide for the convenient insertion of the short inner lever L. This lever is pivoted in a bracket J, secured to the machine frame or base at one end thereof, and is provided upon its upper edge with a metallic strip N, which when said lever is in its proper position between the uprights of the frame, as clearly shown in the drawings, is adapted to bear against the anti-frictional roller journaled in the lower end of the depending arm of the movable platen- Beneath this lever is also arranged a metallic strip O, extending the length of the lever and having its ends bent upwardly and formed into eyes o o. This strip, as will also be seen, is bent downwardly at or near its center, and between this bent portion and the under edge of the lever is inserted a wedge brace or block P, which is adapted to brace the short lever L at the point where the greatest strain occurs. The eye 0 is adapted to pass into the bracket J and registers with apertures (not shown) in the sides thereof, a transverse bolt Q, passing through said registering apertures and serving as the fulcruni of the lever. To the eye o of the lever are pivoted by means of a transverse bolt R links S, the opposite ends of said links being pivoted to a lug or arm m of the upwardly-extending long lever M. This latter lever is also provided at its lower end with a transverse aperture m,which registers with similar apertures 7" j in the bracket J said registering apertures receiving a transverse bolt T, which acts as the fulcrum for the lever.

Another important improvement which I have devised upon the apparatus described in my application for Letters Patent before IOO mentioned is the employment of braces extending over the top of t-he press. These braces in the drawings are indicated by the letters U U and pass over the upper curved surface of the stationary platen, ttin g in suitable grooves formed therein, and their lower straight ends are provided with eyes u u, which receive the transverse bolts Q and T.

From the foregoing description the construction and operation of my improved apparatus, it is thought, will be readily understood. It will be seen that it is much more simple than the device described by me in application for Letters Patent tiled January 15, 1890, Serial No. 336,980, and at the same time greater power is attained with less actual force being expended.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

I. In a cotton-press, the combination, with a base-piece provided with uprights, said up rights having their inner angles or corners provided with metallic facings or tracks, ot a stationary platen connecting the upper ends of said uprights, a lower vertically-moving platen or follower working between the uprights, provided with extended ends having angular notches therein which fit the tracks of the uprights, and also provided with a depending central arm, arms secured to the opposite sides of the latter arm and provided with bent ends littng the tracks of the uprights, an inner short lever fulerumed at its forward end, arms secured to said central arm and embracing the said lever, a long lever suitably fulerumed to the frame of the machine and provided at its forward end with an extending lug or arm, and links connecting the short lever with said extending lug or arm, substantially as set forth.

2. In a cotton-press, the combination with a base-piece provided with uprights, of a stationary platen connecting the upper ends of said uprights, a lower vertically-moving platen working between the uprights and provided with a depending central arm, said arm terminatingin a series of auxiliary arms, an anti-frictional roller journaled between the same, alever engaging with said anti-frictional roller, and means lfor operating said lever, substantially as set forth.

In a cotton-press, the combination, with a basespiece provided with uprights, of a stationary platen connectingr the upper ends of said uprights, a lower vertically-moving platen or follower working between the uprights and provided with a depending central arm, an inner short lever provided upon its upper edge with a central metallic facing, arms secured to said central arm, embracing the said short lever, a metallic strip arranged beneath the lower edge of the lever and terminating at opposite ends in eyes, brackets secured to the base-piece and provided with transverse apertures, a transverse bolt passing through the registering eye and apertures of one of, the bracket-s and forming the pivot of the short lever, a long lever provided with an arm or lug and having its other end titting in the other bracket and provided with an aperture, a transverse bolt passing through said aperture and through the apertures of the rear bracket, and links pivotally conneeting the rear eye of the longitudinal strip with the upwardly-extending arm of the long lever, substantially as set forth.

4. In a cotton-press, the combination` with a base-piece provided with uprights, of astationary platen connecting the upper ends of said uprights, a lower vertically-moving platen or follower' working between the upright-s and provided with a depending central arm, an inner short lever provided upon its upper edge with a metallic facing, arms secured to said depending arm, embracing said short lever, a metallic strip arranged beneath the lower edge of the lever and terminating at opposite ends in eyes and provided at or near its center with a bent portion, a wedge brace or block inserted between said bent portion and the under edge of the lever, a transverse bolt passing through an eye in the metallic strip and forming the fulerum of the lever, a long lever fulcrumed in the frame of the ma chine, and a link pivotally connected with the lower end of said long lever and with the metallic strip, substantially as described.

5. In a cotton'press, the combination, with a base-piece provided with uprights, of astationary platen connect-ing the upper ends ot' said uprights, a lower vertically-moving platen or follower working between the uprights and provided with a dependingcentral arm, an in- 11er short lever provided upon its upper edge with a central metallic facing, arms secured to said central arm, embracing said lever, a metallic strip arranged beneath the lower edge of the lever and terminating at opposite ends in eyes, brackets secured to the base-piece and provided with transverse apertures, a transverse bolt passing through the registering eye and apertures in one of said brackets, a long lever provided with an arm or lug mounted in the other bracket and provided with an aperture, a transverse bolt passing through said aperture and through the apertures of the bracket, links connecting an eye of the longitudinal strip with the arm of the long lever, and U-shaped braces passing over the upper curved surface of the stationary platen, the straight ends of said braces provided with eyes through which the transverse bolts pass, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
